Re erring to'the drawings :--Figure- 1 is a'side' view of a' magazine ofa weft replen ishing Application filed To all whom it may concern: Be it known that I, EPPA H. RYON, a citizen of the United States, residing at Waltham, in the county of Middlesex and State of Massachusetts, have invented cert-am new and useful Improvements in Transfer Mech-. anism for Weft Replenishing Looms of which the following is' a specification. My invent-ion relates to the filling transfer mechanism of weft replenishing looms, and the object of my invent-ion is to improve upon the transfer mechanism, as ordinarily made, which transfers a fresh bobbin from the magazine into the running shuttle on the same pick on which the practical or substantial or total exhaustion of filling on the bobbin is indicated by the filling feeler or detector.

My "nvention consists in certain novel features of construction of my improve ments' as will be hereinafter fully described. In my improvements in transfer mechanism for weft replenishing looms, the trans ferrer is operated at the proper time, through intermediate connections, by a driven cam, preferably located on the bottom shaft of the loom. The transfer mechbined therewith; the magazine is partially broken away, and the lay is shown in section. Fig. 2 is a section, on line 2,2, Fig. 1, of thetransferrer leven'and some "detached parts of the magazine, looking in the direction of arrow a, same figure. Fig. 3' shows, on an enlarge scale, some of the parts shown in Fig. 1, in a ditferentposif tion. Fig. et corresponds to Figu3, but shows the parts shown in Fig. 3, ina different position, and, Fig.5 corresponds to Fig. 4, but shows the parts shown in Fig. 4 in a different position.

In the accompanying loom side or end frame, 2 is the lay carried onthe' lay sword. 3, which i is pivotally mounted at its lower end, not shown, and is operated through the crank connector 4 to the crank shaft 5; 6 is a single stationary and 10 a shuttle therein, carrying a bobbin 11 having filling l1 thereon; 12 is the bottom shaft, 13 is a stand rigidly secured to the loom side 1, andhaving a cylindrical bobbin=from the .magazine into the active shuttle on the substantial or practical exhaustion of the filling in said shuttle, on 14: of the rotary 14! to carry the The stud 15 on mounted thereon the arm 16.

17 is the feeler bed, adjustably secured on the stud '18 b 'a screw 'bolt 19. The guide or bed 17 is preferably grooved on its upper side to'loosely receive the feeler slide-20, which is adapted to engage the filling 11 on a bobbin 11. in the running shuttle 10. The slide 20 is adaptedto operate, through magazine, having ockets heads ofthe bobbins 11.. the stand 13 has loosely or filling detector, comprising hub of the transferrer preferably a longitudinally movable slide, which is adapted to enter an opening in the front wall of the shuttle to engage the filling therein. The filling feeler or filling-detector is located on the magazine end of the loom.

I have shown in the drawings a detached portion of a weft replenishing loom, having a. rotary magazine, and a filling detector, and my improvements in transfer mechaintermediate connections, the upright lever nism combined therewith, sufficient to en- 21, whichha's its hub 21 able those skilled in the art to understand 22, which is loosely mounted. in bearings 23' the construction and operation thereof. ,The on the-stand: 23.

One end of, a rod 25 is pivotally connected to the upper end of an upright lever 24; the other end of said rod 25 is adapted to bear against a lug 26 on a downwardly extending latch 26, which has its hub 26 pivotally mounted on astud 27, see Fig. 2, on the transferrer arm 16. A helically coiled contraction spring 28 has one end connected to in this instance loosely supported at- 23" inthe arm or stand 23 attached-to the loom side, and has an up and down movement in" a vertical plane. Thelower end of the arm 6 -29 has a boss 29'r'*t hereon, which is adjustably connected by a nut; 30 to the upper end of a rod 30; the lower end of the rod 30 is pivotally connected to one arm of an angle lever 3l,see Fig. 1,which has its hub loosel-y mounted on a stud 32 on the loom side The other arm of the angle lever 31 has pivotally connected thereto one end of a rod or 7 connector the other end of said rod or connector-33 is connected to one" arm of a double lever 34, which has its hub loosely mounted on a stud, 35 on a stand or hanger 1 on the loom side. 1. The second arm 34- of the double lever 34 carries a pin 36, on

' which is mounted in this instance a roll 37,

which is adapted to engage'the periphery of and be operated by a 'cam 38, in this instance fast on the bottom shaft12.

A helically coiled contraction spring 39 has its upper end-connected 'to the stand 23, and its'lower end connected to a collar 40, secured on the lower end of the rod 30 by a set screw 41'. The sprin' 39 acts to yieldingly hold the roll'37 on t e operating lever 34 in engagement with the cam 38.

The boss 16 on the end of the t-ransferrer arm 16 has a stud 42 extending out therefrom, see Fig. 2, on which is hinged or pivotally mounted, the yoke shaped end 43' of the downwardly extending transferrer member 43, which is adapted to engage-with its lower engaging end 43" the bobbin 11 in the magazine, on the downward movement of the transferrer arm.16. A collar 44 secured on the stud 42 by a set screw 45, acts to hold the transferrer member 43 in position. Ahelically coiled torsion spring 46 encircles the stud 42, and is connected at one end to the hub 43 of the transferrer mem-' ber 43, and at its other end to a collar 41,. secured by a set screw 48 on the stud 42, and

acts to yieldingly hold the transferrer mem- Through ber 43 against a stop or rest 49, secured to' the cylindrical portion of the magazine, in this instance by screws 49. The stop 49 serves as a guide for the transferrer member 43, and on the downward movement of the transferrer arm 16 and the transferrer member 43, the stop or rest 49 engages the inclined or beveled portion 43" on the transferrer member 43, and causes said member, as shown in Fig. 5,'to be moved backwardly to follow the movement of the lay, thus insuring the positive insertion of afresh bobbin from the magazine. into the 7 active shuttle.

The operation of my improvements will be readily understood by those skilled in the art, and briefly is as follows :-As long as the loom is running n0rma-lly,'and a bobbin hus'la sufiicient". amount of filling thereon, as shown in Fi s.;l and 3,-the 'feeler slide 20, on the forward movement of'the lay, will engage the filling andmove backviiardly the .upright levers21. and 24, and through the' Wire and Spring ,:the 1atch-26will be j' moved out of the pathofthe hooked end 29' on the vertically moving bar 29, shown in Fig. 3, and leave the transferrer 16 at rest, and in its raised position, an extension 161"on said arm'engaging a check bolt 16*,

see Fig. 3. When the filling, on the bobbin in the running shuttle is practically or substantially exhausted, as shown in Fig.4, the filling feeler slide 20 will not move back the upright levers 21 and 24, but will leave them at. rest, with the lower end'of the latch 26 in the path of the vertically moving bar 29, so that on the downward movement of said bar'29, through intermediate connections to the cam 39, said latch 26. will be drawn downward, and also the transfcrrer arm 16 of the transferrer member 43, to force a b'ob-' loin from the magazine into the active shuttle to take the place of the substantially exhausted bobbin therein, and on the continued downward movement of the transferrer arm' 16 and the transferrer member 43,. the exhausted bobbin will be removed from the shuttle, and substituted by a fresh bobbin, and as the rest or stop 49 engagesthe inclined-portion 43 on the transferrer arm 43, said member will be forcedbackwardly to follow the continued backward movement, of the lay, and insure the insertion of the fresh bobbin on the samepick.

The advantages of my improvements will be readily appreciated by those skilled in the art. I

My improvements, "to be combined with the filling detecting mechanism, and the.

, ing looms of the ordinary type, without materially altering the construction of said looms.

One of the essential features of my im provements is the constant reciprocating device 29, which may be so timed and adjusted as to immediately cooperate with the transferring mechanism on the indication of the feeler, to cause a transfer of new filling into the active shuttle.

, I believe that I am the first one to use a filling feeler on the magazine end of a loom, and on a stationary part of a loom, to de feet the condition of filling when the lay is at its extreme front center, and immediately transfer a fresh bobbin into the active shuttle, before the shuttle is picked from the magazine end of the loom.

It will be understood that the details of construction of my improvements may be varied if desired.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent'is:
